While I like the new plan mode very much, there must always be a fly in the ointment. For example, for my current location and date, the sun sets at 19:19 and rises at 7:35 (we are on daylight saving time). If I try to create a new plan in the SeeStar app, the earliest time I can chose is 21:00 and the latest 05:50. The usable night interval is usually from half an hour after sunset to half an hour before sunrise, so 20:00 to 7:00 in this case. This means that I lose more then an hour at the beginning of the night and another hour at the end for no good reason, just because ZWO says so. That's almost two hours and a half, and as we go into summer this will represent a very significant portion of already short and rare good astrophotography time.
So ZWO, please remove this useless limitation ASAP. If you have to set limits at all, use sunset and sunrise times and let the user decide when to use the telescope.
